Abstract
1. Устройство для измерения физико-механических свойств материалов, содержащее пьезоэлектрический стержень с двумя внешними и одним разделительным электродом, индентор, размещенный на одном из концов стержня, держатель, в котором укреплен другой конец стержня, схему возбуждения, схему детектирования и управляемый источник напряжения, отличающееся тем, что пьезоэлектрический стержень выполнен составным из закрепленной в держателе и свободной частей, причем свободная часть выполнена как продолжение закрепленной и скреплена с ней, управляемый источник напряжения подключен к закрепленной части, индентор размещен на конце свободной части, один внешний электрод свободной части стержня соединен со схемой возбуждения, другой внешний электрод соединен со схемой детектирования. !2. Устройство по п.1, отличающееся тем, что оно снабжено дополнительным пьезоэлектрическим стержнем, аналогичным свободной части составного стержня таким образом, что они все вместе образуют камертонную конструкцию, в которой закрепленная часть составного стержня является ножкой камертона, а свободная часть составного стержня и дополнительный стержень образуют ветви камертона, причем схемы возбуждения и детектирования подключены к разным ветвям камертона. 1. A device for measuring the physicomechanical properties of materials, comprising a piezoelectric rod with two external and one separation electrode, an indenter located at one of the ends of the rod, a holder in which the other end of the rod is mounted, an excitation circuit, a detection circuit, and a controlled voltage source, characterized in that the piezoelectric rod is made of composite fixed in the holder and the free parts, and the free part is made as a continuation of the fixed and fastened with it, control The voltage source to be connected is connected to the fixed part, the indenter is located at the end of the free part, one external electrode of the free part of the rod is connected to the excitation circuit, and the other external electrode is connected to the detection circuit. ! 2. The device according to claim 1, characterized in that it is equipped with an additional piezoelectric rod, similar to the free part of the composite rod so that they together form a tuning fork structure, in which the fixed part of the composite rod is the fork of the tuning fork, and the free part of the composite rod and the additional rod form the tuning fork branches, and the excitation and detection circuits are connected to different tuning fork branches.
